I'm going to be watching MacRumors.com liveblog since they always seem to be the fastest. Though the funny liveblog commentary from the guys at Gizmodo (live.gizmodo.com) is usually good too.
I'll pick up the stable release from the last announcement.
I have bought five iPods and two Macs over the last five years. One of the Macs was new, but the rest were used or refurbished models that were at least a year old at the time of purchase.
It's a good way to save a little money and to watch the issues shake out. And Apple's refurb store is great.
Which is not to say I won't load up some Apple sites later today to find out what I'll be shopping for next year. :)
When everyone is out buying brand new versions that will break, I'll pick up the stable release from the last announcement. :-)
